I remember mine were the same way. I don’t have my VS close so I don’t quite remember, but I think I went up a length on the rivet. The rivets Vans call out are the ones you drove. I checked with a friend on his flying -10, and his has the rivets Vans calls out, no issues. There’s a few places in the plans that use a rivet call out that don’t quite make a spec shop head.
